River Ryan, Jazz Chisholm, and Baseball’s Most Injured Teams

Thanks to the trade deadline, this is a quiet time of the year for transactions, but baseball’s injured list is always hopping, and Tuesday was sadly no exception. First came the announcement that Dodgers pitching prospect River Ryan, our 21st-ranked prospect on the Top 100, would require Tommy John surgery, ending his 2024 season, and at best keeping him out for the vast majority of 2025. Not to be left out of the UCL injury party, Jazz Chisholm Jr. injured his left elbow on a slide into home plate on Monday night. The exact severity of Chisholm’s injury is still unknown, but with the season rapidly reaching its conclusion, any significant time on the shelf could imperil his ability to help the Yankees in their playoff push this year.
Chisholm was easily the biggest addition the Yankees made at the deadline, a flexible offensive player who the team hoped would bring some emergency relief to an extremely top-heavy offense that has received an OPS in the mid-.600s from four positions (first base, second base, third base, and left field). And Chisholm was more than fulfilling that expectation, with seven home runs in 14 games on the back of a .316/.361/.702 slashline. As noted above, the full extent of his injury isn’t yet known, but in a tight divisional race with the Baltimore Orioles (and with a playoff bye at stake), every run is precious. The Yankees have had a curious amount of misfortune when it comes to the health of their deadline acquisitions in recent years; between Frankie Montas, Scott Effross, Lou Trivino, Andrew Benintendi, and Harrison Bader, you might get the idea that they mostly acquire medical bills in their trades.
Meanwhile, the Dodgers, as is often the case for the team, have had more than their share of pitching injuries, with the IL rotation of Walker Buehler, Yoshinobu Yamamoto, Tony Gonsolin, Dustin May, and Emmet Sheehan likely superior to most team’s healthy rotations. With so many injuries, the Dodgers promoted Ryan to the majors. He was solid (if occasionally wild) in his 5 1/3 inning debut against the Giants, and his one-run, eight-strikeout effort against the Astros guaranteed he’d get more starts as long as he performed. Unfortunately, he was only able to make two more starts before he hit the shelf; he was removed in the fourth inning of Saturday’s game against the Pirates due to forearm tightness. The returning Buehler is expected to start on Wednesday, giving the team a rotation of him, Tyler Glasnow, Jack Flaherty, Clayton Kershaw, and Gavin Stone — at least until someone hurts an elbow, tweaks an oblique, or gets run over by a cartoon steamroller.
The Dodgers have been enormously resilient in the face of their injuries, making their 71-49 record, the best in the National League, even more impressive than it would be otherwise. But they likely don’t find the scene in their rear view mirror to be a pleasant one, with the Diamondbacks and Padres both going on a tear in recent months. Despite going 15-10 over their last 25 games, a 97-win pace over a full season, the Dodgers have seen their eight-game lead slashed in half. Other teams with injury issues have been less successful, with the Atlanta Braves coming most immediately to mind. While the general encrapification of much of their offense shoulders a good bit of the blame, Atlanta has suffered a number of injuries to key players, most notably 2023 NL MVP Ronald Acuña Jr., as well as rotation stalwart Spencer Strider.
So do the Dodgers and Braves actually have the best case for cursing the injury gods? And where do the Yankees stack up? Since I’m always looking for an excuse to bring some extra nerdery to my baseball analysis, this seems like a good time to check in on which teams have lost the most value due to injury or, at least, have the most value on the IL instead of the lineup card. To do this, I took the missed time for all 622 players who have appeared on the IL this year, calculated a full, healthy WAR projection in ZiPS at the time of their injury, and then pro-rated for the actual missed time so far. Note that this is the potential value lost to injury, not necessarily the number of lost wins, since teams with a lot of injuries naturally couldn’t play everyone full-time in a healthier scenario. Trying to unwind injuries to do that would create a lot of impossible counterfactuals, such as trying to figure out how quickly the Yankees would have turned to Luis Gil if Gerrit Cole had been healthy to start the season. Let’s dive in:
| Team | Lost Potential WAR |
|---|---|
| Los Angeles Dodgers | 13.96 |
| Atlanta Braves | 9.96 |
| Texas Rangers | 9.47 |
| Boston Red Sox | 9.04 |
| Miami Marlins | 8.92 |
| Houston Astros | 8.27 |
| Tampa Bay Rays | 8.19 |
| Milwaukee Brewers | 7.11 |
| Arizona Diamondbacks | 6.99 |
| New York Yankees | 6.50 |
| Cincinnati Reds | 6.46 |
| Pittsburgh Pirates | 6.31 |
| Cleveland Guardians | 6.30 |
| Chicago White Sox | 6.13 |
| San Francisco Giants | 6.06 |
| Oakland Athletics | 5.77 |
| Chicago Cubs | 5.38 |
| San Diego Padres | 5.25 |
| New York Mets | 5.15 |
| Baltimore Orioles | 4.70 |
| Minnesota Twins | 4.68 |
| St. Louis Cardinals | 4.41 |
| Los Angeles Angels | 4.18 |
| Seattle Mariners | 4.12 |
| Colorado Rockies | 4.06 |
| Philadelphia Phillies | 3.75 |
| Washington Nationals | 3.20 |
| Detroit Tigers | 2.72 |
| Toronto Blue Jays | 2.51 |
| Kansas City Royals | 1.92 |
I swear, on my inalienable right to refuse to eat Cincinnati-style chili, that I didn’t put my thumb on the scale to have the Dodgers and Braves come out on top here. Remember, this doesn’t mean the Dodgers actually lost 14 wins, or that they would have been 85-35 if healthy, only that they lost that many potential wins. There’s no plausible way that they could have fully utilized a healthy Glasnow, Stone, Yamamoto, Kershaw, Miller, Buehler, Gonsolin, and May simultaneously.
Also ranking highly are the Texas Rangers, whose plan to have a bunch of injured starting pitchers make triumphant returns around midseason will probably turn out to be too little, too late. The Red Sox have been surprisingly resilient at the edges of the playoff race, and they’ve done so having lost Lucas Giolito, Trevor Story, Triston Casas, and Garrett Whitlock. The Marlins losing most of their rotation during the spring is a well-known disaster, and the Astros had to weather a lot of their starters missing time in the early months of the season.
On the flip side, the Royals have been quite fortunate with their injuries, with ZiPS not seeing a single one as particularly impactful. That the Blue Jays and Tigers have generally stayed healthy makes their respective seasons look a lot more depressing; they actually had the guys they wanted on the roster available. Good health aided the Nationals in remaining tantalizingly close to relevance through the season’s early months, and while the Phillies endured six-week IL stints from Trea Turner and J.T. Realmuto, they’ve largely avoided serious injuries that would have tested their offensive depth, especially in the outfield. As for the Yankees, despite the perception that they’ve been bit especially bad by injuries, the estimate of 6.5 potential wins lost only ranks 10th in the league, a half-win above the average of 6.0. Cole was a big one, and poor health has plagued much of their bullpen, but the losses here weren’t notably debilitating compared to the typical team.
When evaluating team projections at the end of the season, which players actually end up getting playing time is just as crucial in predicting a team’s record as how accurate the individual projections are. While teams have gotten considerably better over the last 20 years at identifying which players are good at baseball, figuring out how to keep everyone healthy is still baseball’s El Dorado. Until that unlikely day, injuries will continue to be the bane of teams’ (and fans’) existence, and we’ll continue the tally.

Surprised by the Orioles (low) total. Westburg and Bradish alone are major hits, then add Grayson Rodriguez, Wells, Means, Mateo, and Coulombe…pretty harsh
and Bautista
I think that really speaks to the depth of the O’s organization, that there wasn’t too much drop-off in projections between those injured guys and the guys who replaced them.
Was that how this was calculated? My understanding was that it was not, but rather just the missing WAR. So who might replace guys was irrelevant.
Agree, but it’s partly because Rodriguez and Westburg are relatively recent injuries (assuming I’ve understood the methodology properly).
I did a quick total, and I think 4.70 fWAR isn’t all that far off
Westburg ~1.0
Bradish ~2.0
Rodriguez ~0.5
Wells ~0.5
Means ~0.5
Mateo ~0
Coulombe ~0.5
If Bautista is included, then yes, it’s a firm undershoot. But I don’t think he is?
Yeah would be unfair to include Bautista. He was never part of this team’s plan for 2024.
Bradish was at 1.4 war through 8 starts when his season ended. Where are you getting this from?
I eyeballed it? I also thought 4.70 fWAR was an underestimate, so I thought through each of the major injury losses and guesstimated how much fWAR they might have accumulated in the stretch they missed.
Bradish was on pace to cover their estimate by himself.
Then ZiPS didn’t project him to keep up that pace. His current page projects him for 0.5 WAR in 30 IP RoS, so if he had pitched 120 more IP instead then that’d be the 2.0 WAR tdmoc eyeballed.
Excellent.
I have come to the conclusion that it is not just bad luck that the Dodgers keep losing pitchers to the IL, and often for long periods of time.
My theory is this: The Dodgers (and Rays, although that was mostly last year) have these pitching labs that lets them level up pitchers. But whatever they are teaching these guys to do also looks like it is putting huge stress on their bodies. River Ryan, Nick Frasso, Kyle Hurt, Emmett Sheehan, Dustin May, Tony Gonsolin…even Walker Buehler. Pretty much the only young guys who haven’t blown something out in the last 2-3 years while starting are Bobby Miller (who has also been plagued by injuries this year), Julio Urias, Landon Knack, and Gavin Stone.
Here’s the alternative theory: It’s possible that the Dodgers’ issues stem from scouting rather than development, that they just don’t care that much about the risk factors that other teams care about. There’s some evidence for this too–they traded and signed Glasnow, and I think both Maeda and Ryu had a bunch of injury-related issues.
But even then, I don’t think we can just wave this away and say “it’s bad luck.” This is an issue that seems to be affecting all of their pitchers over multiple years. Whatever is going on, the Dodgers are doing something where they think the cost of injury is worth the gains the pitchers are getting.
It seems clear it’s not merely a coincidence. The Rays traded Willy Adames for Drew Rasmussen, now returning from an internal brace procedure, at the time already a double TJS guy.
The only reason why Rasmussen wound up with the Brewers is that the Rays had picked him previously but decided not to draft him because they thought he would need Tommy John.
But that whole situation was super weird because the Rays waited too long to trade Adames, letting his vision problems at the weird TBR ballpark tank his value before finally giving up on him. And it still might work out for them okay because Rasmussen has two more years of service time. If they can just keep him healthy until next year’s trade deadline–a big if–there will be teams who will forget that he’s had two TJ surgeries and an internal brace.
It also seems pretty damn weird to me that Ryan was experiencing forearm tightness in the 3rd and they let him pitch through it.
Sounds like he didn’t tell them because he didn’t want to come out.
He was apparently using a massage gun on his arm between innings, so it seems unlikely the coaching staff didn’t know. Though maybe they weren’t watching.
I would say being in first place in the most competitive division in mid-August despite the obvious production lost to injuries this year is the evidence that the “something where they think the cost of injury is worth the gains” is warranted.
I guess, although the world where they did something slightly less crazy with their starters might allow them to be even further ahead. It’s hard to say, or even whether the Dodgers realize they are making that tradeoff. They probably are aware of it, but that seems even more cynical than leaving it ambiguous.
The idea that driveline style pitching development leads to a lot of success and injuries is acknowledged by front offices. The Cubs were terrible for years at pitching development and Jed Hoyer told the press a few years ago that they didn’t pursue this style of development specifically because they were worried about the injury risks.
They focused on “pitchability” rather than stuff, because they wanted to get a few relatively injury free pitchers and then supplement through free agency. In the end, they didn’t get anything and it ended any chance of a dynasty. Now just about every team embraces driveline and injuries are worse than they’ve ever been.
Yes, but there does seem to be a continuum. Some teams have huge numbers of injuries and others have relatively few. You could probably say those other teams probably have fewer pop-up pitchers, but there are other teams like the Brewers and Guardians that seem to have found a good middle ground.
This is the theory I subscribe to, except I think it’s risk management rather than scouting. IMO they are deliberately stockpiling riskier assets that they believe are trading at a discount. Junk-bond pitching.
I believe it is both. This is part of friedman’s style which is essentially chase the highest upside regardless of risk. But they also prioritize velo development and hard breaker development that is a clear factor which adds stress on pitchers
100% correct.
Jazz was playing the best baseball of his career damn shame he got hurt and the Dodgers are just snakebit with pitching young, old whatever. I could see the Yankees grabbing Amed Rosario they were interested in him in the offseason.
I’m holding out hope that he’ll be able to play through the injury since it’s not his throwing arm.
The Dodger maladies have truly been astounding; Kershaw/Buehler/Miller/Gonsolin/Ryan/May/Sheehan/Yamamoto/Glasnow/Phillips/Treinen/Graterol have all been on the IL (most for the entire season), and they’ve also been without Betts and Muncy for months, as well as Freeman for a couple weeks. And as of today, the NL West is the only division to have *four* .500 or better teams, so their 4 game lead is pretty impressive to me (I notice Dave Roberts gets a lot of crap, but he seems to keep them pretty steady and consistent).
I did not see the ’24 Dodgers getting >125 ABs from Cavan Biggio and Nick Ahmed; baseball is hilarious
Of course the teams chasing them have also been missing their best pitchers(Darvish, Musgrove, Rodriguez, Kelly) for large swaths of the season, not to mention their best bats(Tatis Bogaerts, Lawlar, Walker, Moreno)
Does the braves number seem light? Strider was projected for 4.7 wins this year and missed the entire season, Acuna was at 7.4 and will miss over 2/3 or roughly 5 wins. Those two alone account for total on that table without accounting for multiple months of no Albies, Murphy, Fried, and Harris.
I think that is explained by the calculation being based on projected WAR at the time of injury and scaled for time missed so far. Acuna’s WAR projection at the time of injury was surely lower than 7.4 since he had a bad start. And obviously neither he nor Strider have missed the full season yet.
thank you thats it, i am figuring the full season since we know strider, acuna, and albies are out for the rest of the season….but it hasnt happened yet.
I may review this at the end of the season, but it’s really hard to do now because while projecting some players to play 0 games the rest of the year would be trivially easy, I’d have to project EVERYONE, which sounds like an absolute nightmare.
no that makes sense, please dont spend time doing that.
Albies is not out for the season. He is expected back mid-September.
The Rockies are in the unusual situation where their number would actually be lower if Bryant had spent the whole year on the IL given he’s put up -0.7 fWAR when he has played.
Given that there are 65 hitters and 25 pitchers with -0.5 fwar or worse, it is not particularly unusual.
There are only three teams (Brewers, Orioles, Twins) whose worst player is better than -0.5 fwar.
Fun fact: 7 of those hitters play for the White Sox. One team has 10% of the hitters with -0.5 fWAR or worse.
(They also have two pitchers, but that one is more in line with what we would expect. The D-Backs have four!)
I’m surprised the White Sox have lost six potential wins to injury. A bunch of that is Robert missing about half the season, but where else did they have six potential wins on their roster?
1.6 Moncada, 1.3 Robert, 0.9 Stassi, 0.6 Clevenger, 0.4 Jimenez, and a bunch of bits and bobs here and there (Foster, Lambert and so on)
On my deep rebuild team, I lost both Ryan and Chisholm. Is this why I love fantasy baseball?
“There’s no plausible way that they could have fully utilized a healthy Glasnow, Stone, Yamamoto, Kershaw, Miller, Buehler, Gonsolin, and May simultaneously.”
In all sincerity, I’d love to see an 8-man rotation on 4 days rest, each pitching 4-5 innings. That would leave a couple bullpen spots for specialists and mop duty. If nothing else, it would be a wild experiment.
Mister Dan, how hard would it be to look at, say, the dodgers pitching staff under this lens and see what it could accomplish?
We might see some version of it real time next year!
After the fizzling of the fireman revival some few years ago I don’t think the Dodgers, who are equipped for it, are forward- or left field-thinking enough to actually try. Especially since they’d also have to structure their entire minor league scouting and training system around the idea to make it more than a one- or two-year aberration.
Still, I wish they or another team would. Less stress more frequently seems like a potential way to keep guys from breaking so much, as well as keep everyone relatively fresh over the course of the season.
Actually the way to go would be a “7 man” rotation with each starter having a designated day of the week they start.
Friday- Ohtani
Sat – Glasnow
Sun – Yamamoto
Tues – Miller
Wed – Buehler
There are off days on Mondays or Thursdays each week so the Monday starter could be a guy like May coming back and the Thursday guy a Gonsolin. They’d work out of the bullpen in weeks they don’t start.
This schedule is similar to what you see in college and Japan.
The benefit is the best extra days of recovery allow the pitchers the fully recuperate and lessens the impact of their poor mechanics which are directly leading to injuries (the picture above of Ryan is a perfect example of a pitcher not getting their throwing arm into the proper position).
I’m surprised that the Twins are so low, with their constant Buxton / Correa / Lewis issues.
Part of that is that none of them have missed all that much time individually, and that it’s not an accounting of the full year’s WAR, just the WAR that -theoretically- would have been produced to this point.
Dodgers injuries should be far from a surprise. It’s been largely on pitching side outside of betts/muncy (and muncy is old and was dealing with injuries in offseason). They prioritize velo development over anything. They view picking up high upside/high risk vets as some kind of undervalued thing. It sometimes works out but its not just some random crapshoot they are often hurt
For the Tigers, it’s who got hurt more than how many. Losing Greene and Carpenter (and having Torkelson regress) decimated the middle of their order. Not sure how many other teams could go two months without their 2-3-4 hitters. (And bad when a Baez injury is actually a net positive.)
